Life Goes On is my favorite level that I've designed for the collab. The gimmick of death-platforming was inspired by the gameplay in Life Goes On: Done to Death, which was LPed by raocow a few years ago. In fact, it's one of several levels that I ended up making for AAT that were inspired by console/indie games that I've played, rather than being influenced by other SMW hacks or emulating a particular SMW hacker's level design style. Since replaying parts of the level over and over again is inherent to the gimmick, I tried to keep things short so that it doesn't overstay its welcome. It's possible to die to the shell in midair near the end, but it's tricky without accidentally pulling off a shell jump instead (the one time it is easy to do). And yes, the level also accounts for when the player is Iris. We can't forget about the green one.

A Dream of Green Apples gives off a lot of ASMT vibes - one reason is that it has the same music speed up silliness as PANIC PUZZLE. I think the choice of palettes also helps sell it, and a lot of Catabo's other levels do similar things with colors (e.g., get down and Red Radish).
